when fossils fuels are burned what is their chemical potential energy converted into?

Answers

Answer 1

The chemical potential energy is converted into electrical energy.

Answer 2

Final answer:

When burned, the chemical potential energy of fossil fuels is converted into thermal and light energy. This transformation occurs through the combustion process, creating carbon dioxide and water while releasing heat. Fossil fuels represent a way of storing energy from ancient sunlight, transformed over millions of years under high pressure and temperature.

Explanation:

When fossil fuels such as coal, oil, and natural gas are burned, their chemical potential energy is primarily converted into thermal energy (heat) and light energy. The process of burning is essentially a chemical reaction where these fuels combine with oxygen (O2) to form carbon dioxide (CO2) and water (H2O), releasing energy in the form of heat. This energy release results from breaking the higher energy bonds in the hydrocarbon molecules of the fossil fuels and forming the lower energy bonds of the combustion products.

Fossil fuels are considered a form of long-term storage of energy that originated from ancient sunlight. Through photosynthesis, living organisms such as plants, algae, and photosynthetic bacteria captured solar energy, which then became chemically stored in the organic matter that, under high pressure and temperature over millions of years, transformed into the various types of fossil fuels we use today. This process indicates why fossil fuels are seen as non-renewable energy sources, as the accumulation of such fuels took an extremely long time and cannot be quickly replicated.

What is one characteristic of a sample of matter that indicates it is a pure substance?

A)It can be separated using by a physical means, such as filtering.B)The components in a pure substance do not have to be in definite ratios.C)If the composition of a sample varies, the sample is a pure substance.D)If the composition of a sample is fixed, the sample is a pure substance

Answers

Answer:

Explanation:

If the composition of a sample is fixed, the sample is a pure substance. According to the law of definite proportions (constant composition), components of a pure substance must be in definite ratios regardless of the source.

If heat is released from water vapor, what phase change occurs? A) liquid to gas B) solid to gas C) liquid to solid D) gas to liquid

Answers

D) Gas to liquid. Vapor would be a gas, and in the process of releasing heat, it turns back into a liquid.

ANSWER: D: GAS TO LIQUID

EXPLANATION: Water vapor is already in a gas form because it is vapor. Anytime heat is released from a gas, it will change forms to be a liquid. It is like reverse condensation.

What is the wavelength of radio waves? A. between 1 x 10-3 and 1 x 10-1 meters B. less than 1 x 10-11 meters C. more than 1 x 10-1 meters D. between 1 x 10-8 - 4 x 10-7 meters E. between 4 x 10-7 - 7 x 10-7 meters

Answers

Answer:

The correct answer option is C. more than 1 x 10-1 meters.

Explanation:

A wavelength is the distance between the successive crests of a wave.

A type of electromagnetic (EM) radiation is called radio waves which have wavelengths that are longer than infrared light in the electromagnetic spectrum.

The wavelength of the radio waves is approximately more than 1 x 10-1 meters.

Therefore, the correct answer option is C. more than 1 x 10-1 meters.

Answer:

More than 1 × 10⁻¹ meters

Explanation:

Wavelength is defined as the distance between the successive crests and the successive trough of a wave.

Radio waves are the type of electromagnetic radiation that have longest wavelength in the electromagnetic spectrum. This wave travel with the speed of light. The wavelength of radio waves is 10³ meters.

So, the wavelength of radio waves i.e. more than 10⁻¹ meters. Hence, the correct option is (c).
